There are the following features, with projected state by the time of the release: - LLAP - first version that is production ready, with some missing features (e.g. ACID support). - HBase metastore - first version, at alpha stage, i.e. might not be production ready. - Beeline-based CLI replacement. - Vastly improved vectorized operators for map join, RS, GBY. - CBO improvements to enable it on more queries and replicate a lot of hive optimizers into CBO, CBO perf improvements. - New versions of Calcite, Log4j, Parquet, Tez, Thrift, ?.. - Lots of commits marked as “Spark Branch”, not sure what these are. - Variety of other improvements for perf and bugfixes (that probably should be backported, I might do a bulk JIRA comment). - CBO return path (not sure of the status yet), avoiding multiple conversions between CBO and Hive. - Removal of Hadoop1 and deprecation of MR (pending) :) - Maybe something I have missed.
